Humidity: the silent enemy that deteriorates goods (and how to neutralize it with certified desiccant systems)
At YDRY, we know that problems caused by humidity are not exceptional, but predictable. Most of the incidents we handle start with products that seemed well packaged, but upon arrival at their destination show mold, corrosion, caking, or physical deterioration.
In this article, we explain:
Why this happens even when it seems that “everything was done right.”
What specific damage it causes in different sensitive sectors.
How to prevent it definitively with certified industrial desiccant systems under DIN 55473 standards.
Why does humidity continue to cause damage?
Even with hermetically sealed packaging, there are multiple ways for humidity to enter or be created within the system:
Hygroscopic materials
Materials such as cardboard, foams, fabrics, wood, or labels can absorb moisture and then release it. This trapped vapor is activated by changes in temperature or pressure.
International transport
On maritime routes, thermal differences create what is known as “internal rain.” This causes relative humidity (RH) to rise to critical levels — 80% or more — generating condensation on the walls of the container and on the product.
Industrial processes without dehumidification
If the product is packaged with an internal RH > 50%, it essentially already contains the problem. A typical example: sealed containers with residual moisture and no desiccant.
Prolonged storage or in humid areas
Pallets in contact with cold ground, warehouses without ventilation, stacks in coastal or tropical areas… What’s the result? A perfect combination for the development of fungi, oxidation, agglomeration, or even loss of functionality.
Real damages according to the type of industry
Let’s go sector by sector so you can quickly identify the risks and the sector-specific solution.
Textiles
Consequences: stains, musty odors, color loss, clumping.
YDRY Prevention: silica gel packets distributed between layers. They absorb up to 30% of their weight.
Food and nutraceuticals
Consequences: clumping, loss of texture, oxidation, discoloration.
YDRY Prevention: food-grade desiccants (in accordance with Regulation (EC) 1935/2004 and Law 17/2011).
Automotive and electronics
Consequences: oxidation on terminals, stains on parts, loss of conductivity, poor assembly.
YDRY Prevention: high absorption desiccant in high RH environments.
How to neutralize the risk: YDRY Method 0 Humidity
Our system is based on 3 technical pillars, all adjusted to meet the DIN 55473 standard and adapted to the hygroscopic properties of the environment.
1. Exact calculation of quantity and type of desiccant
We do not improvise; we calculate based on:
– Volume of the confined space.
– Transit or storage time.
– Type of packaging material (permeability).
– Expected RH and product tolerance.
We use technical calculation formulas and verified absorption curves. For example, the DIN 55473 standard defines how to measure desiccant units based on absorption capacity.
2. Strategic distribution in packaging
The desiccant should be placed where vapor accumulates:
– Textiles: between layers.
– Electronics: next to connectors.
– Jars or blisters: in the upper area (vapor rises).
This way, we increase the efficiency of the anti-humidity system.
3. Validation of the sealing and packaging system
YDRY analyzes and technically evaluates the materials and packaging conditions used by our clients: type of film, quality of heat sealing, condition of boxes, joints, vents, as well as the arrangement of the pallet and its lateral/bottom protection.
Additionally, we recommend the use of visual humidity indicators that allow our clients to verify the behavior of the system during transit or storage.
The solution to your humidity problems
The 90% of cases of humidity damage can be avoided with a well-implemented, professional, and adapted desiccant system.
At YDRY, we don’t deliver “little bags,” but rather complete technical solutions to prevent claims, protect the value of your product, and ensure deliveries without surprises.
Do you want us to help you calculate how many grams of desiccant you need per box, pallet, or container?

FAQ – Frequently Asked Questions
It is a moisture absorption system that meets the requirements of the German standard DIN 55473, which defines desiccant units, absorption capacity, labeling, and accepted materials.
Because physical barriers do not eliminate internal moisture, temperature changes can cause condensation, and the internal or residual hygroscopic material can become activated. A desiccant complements these barriers.
In logistics/export, textiles, food, nutraceuticals, automotive, electronics… in general, in any industry where moisture can compromise the value or functionality of the product.
It is calculated based on the volume of the packaging, the duration of transit, the permeability of the material, and the expected HR. We do the calculations for you and provide a personalized solution with our products.
